Numerous variations, changes, and substitutions will now occur to those skilled in the art without departing from the subject matter disclosed herein. It should be understood that various alternatives to the embodiments of the subject matter disclosed herein may be employed in practicing the subject matter disclosed herein. It is intended that the following claims define the scope of the subject matter disclosed herein and that methods and structures within the scope of these claims and their equivalents be covered thereby.

Needle Insertion Techniques

In the medical field, the need often arises to inject or extract fluids from the body of a patient. Various medical procedures, including, but not limited to, phlebotomies, intravenous therapies, needle biopsies, epidurals, blood transfusions, and depot injections, all require the use of a hypodermic needle to gain access to interior organs. As such, the hypodermic needle is one of the most commonly-used tools in the practice of medicine.

Although so many common medical procedures require the use of a hypodermic needle, the effectiveness of such procedures is primarily reliant upon the proper insertion of the needle. Identifying structural locations under the surface of the skin is often difficult; and, at times, impossible. Variations in the thickness of skin, subcutaneous fat, and numerous other physical variations make it difficult, sometimes dangerous, and occasionally impossible to insert needles in specific locations. Due to such variations, inter-organ access is not impervious to failure, even when conducted by master nurses, skilled phlebotomists, or other doctors who commonly insert hypodermic needles.

Accurate access to interior organs, especially smaller, peripheral veins, is critical to the health and wellbeing of patients. However, smaller, peripheral veins and organs are typically the most difficult to access, especially for patients in the greatest need of intravenous access. For example, renal patients, trauma patients, critically-ill patients, and dehydrated patients require intravenous access; however, due to their health complications, the peripheral veins may be constricted, scarred, or otherwise damaged, thereby preventing access to the lumen of veins, arteries, and/or organs. Moreover, in emergency situations in which intravenous access is prevented, central or intraosseous line infusions, which have a higher frequency of life-threatening complications, must be performed.

Currently, procedures requiring needle insertion are typically performed manually by a physician or nurse. However, the variations in skill and knowledge between and among physicians and nurses, coupled with the inability to view underneath the skin, create a high frequency of error in needle placement.

Various imaging technologies, such as magnetic resonance imaging (MRI) and computer-aided tomography (CT), have been used in guided needle insertion methods. While imaging technology-guided needle placement has increased the likelihood of successful needle placement, it is replete with its own limitations. For example, very few physicians and nurses are taught or independently learn how to insert a needle using the guidance of medical imaging techniques, as only a handful of physician residency specialties, such as surgeons, anesthesiologists, and emergency physicians, encourage the training of imaging technology-guided needle placement. Even with such encouragement, due to the limited focus of such specialties, training of imaging technology-guided needle placement within such specialties is typically limited to central venous access (i.e., large vessels in the neck, chest, and thighs). Since these procedures involve large vessels and large needles, very few, if any, of these specialized physicians are trained to use the same technique to access smaller, peripheral vessels and organs.

Even with proper training, inter-organ access using imaging technology-guided needle placement is difficult in practice. In some cases, current imaging technology-guided needle placement requires the practitioner to use the non-dominant hand for the imaging probe and the dominant hand for the needle, all while looking at an image on a screen set off away from the patient. The multiple, independent variables increase the likelihood of error, even for the most skilled and dexterous practitioner. Accordingly, there exists a need for a medical apparatus for accurate needle insertion, which simplifies the guided, needle-insertion process and requires minimal training and skill.

Disclosed herein are devices, systems, and methods for guided-needle insertion and/or placement. The devices and systems described herein guide a user to insert and/or place a needle at a desired location with the assistance of ultrasound imaging, an infrared sensor, and/or a vacuum source.

In some embodiments, the guidewire-controlling needle slot 232 is hexagonal in shape. In some embodiments, the guidewire-controlling needle slot 232 is connected to a guidewire-containing spindle (not shown in FIGS. 1-12). In some embodiments, the guidewire rests within the insertion device and in the guidewire-containing spindle. In some embodiments, the guidewire-containing spindle and the distal end of the guidewire rest inside the needle. In some embodiments, the guidewire is held in its resting position by a spiral torsion spring (not shown in FIGS. 1-12). In some embodiments, the guidewire-controlling needle slot 232 moves rotationally. In some embodiments, the guidewire-controlling needle slot 232 acts against or with the force of the spiral torsion spring and advances or retracts the guidewire within the needle. In some embodiments, the guidewire is advanced out of the distal end of the needle such that it is advanced flexibly down the target tissue (e.g., a lumen of a target blood vessel) after the needle has already been inserted into the target tissue (e.g., a target blood vessel). In some embodiments, once the distal end of the guidewire is advanced into the target tissue (e.g., the lumen of the target blood vessel), the catheter is advanced forward over the needle and over the guidewire into the target tissue (e.g., the lumen of the blood vessel). In some embodiments, the introduction of a needle, a catheter, and/or a guidewire using the devices, methods, and systems described herein is consistent with the Seldinger technique. The Seldinger technique is a medical procedure used to obtain safe access to blood vessels and/or hollow organs. In some embodiments, the devices, methods, and systems described herein improve the success of insertion of a needle, a catheter, and/or a guidewire into the lumen of a target tissue (e.g., a blood vessel and/or a hollow organ).

In some embodiments, the distal ball joint 221 a of the second control arm 218 b connects to a second collar spring 216 b. In some embodiments, the second collar spring 216 b is located at the base of the distal portion of the cartridge 234 a and adjacent to the proximal portion of the cartridge 234 b. In some embodiments, the second collar spring 216 b is enclosed in a casing.

In some embodiments, the first control arm 218 a and the second control arm 218 b allow for simultaneous free rotation in two planes while preventing translation in any direction. In some embodiments, the first control arm 218 a and the second control arm 218 b allow for a degree of rotation in movement of the proximal portion of the cartridge 234 b with respect to the distal portion of the cartridge 234 a.

In some embodiments, the proximal portion of the cartridge 234 b comprises a first arm 230 a and a second arm 230 b, as shown in FIG. 8. In some embodiments, the distal portion of the cartridge 234 a comprises a first notch 231 a and a second notch 231 b, as shown in FIG. 8.

In some embodiments, the cartridge 234 comprises one or more suction valves. In some embodiments, the cartridge 234 comprises a first suction valve 208 a and a second suction valve 208 b, as shown in FIG. 8. In some embodiments, the first suction valve 208 a and a suction valve 208 b are one-way valves. In some embodiments, the suction valve is controlled manually.

In some embodiments, manual control of the vacuum action of the cartridge is controlled by the user.

In some embodiments, the cartridge 234 comprises a vacuum button or a vacuum bulb (not shown in FIGS. 1-12). In some embodiments, the surface of the vacuum button or the vacuum bulb is a pliable membrane. In some embodiments, the pliable membrane is composed of a shape-memory polymer. In some embodiments, the user activates the vacuum button and/or the vacuum bulb to activate the suction. In some embodiments, the vacuum button is a flexible, dome-shaped button. In some embodiments, the vacuum bulb is a flexible bulb. In some embodiments, the user depresses the vacuum button or the vacuum bulb to initiate suction. In some embodiments, once depressed, the area under the vacuum button is decreased thereby displacing the air under its surface (e.g., a membrane), which pushes that air through the first suction valve 208 a to outside of the outer edge of the cartridge 234. In some embodiments, once the pressure exerted by the user onto the surface of the vacuum button and/or vacuum bulb is the released, the vacuum button and/or vacuum bulb returns to its original shape, creates an area of low pressure under the vacuum button and/or vacuum bulb, and consequently draws air through the second suction valve 208 b from the suction area under the cartridge, between the cartridge and the surface of the skin of the patient.

Alternatively, in some embodiments, the cartridge comprises a manually controlled centrifugal pump. In some embodiments, the centrifugal pump comprises an impeller. In some embodiments, the user mechanically activates the impeller by depressing a button. In some embodiments, the depression of the button causes a rotation of the impeller to start. In some embodiments, the rotation of the impeller pushes air out of the first suction valve 208 a to outside of the cartridge, thereby creating an area of low pressure in an impeller chamber. In some embodiments, the low pressure draws air through the second suction valve 208 b from the suction area under the cartridge, between the cartridge and the surface of the skin of the patient.

Alternatively, in yet another embodiment, the vacuum button and/or the vacuum bulb is automatically activated by the insertion device. In some embodiments, an actuator of the insertion device causes the depression of the vacuum button and/or the vacuum bulb on the cartridge.

Alternatively, in other cases, the vacuum between the surface of the skin and the cartridge is created by a vacuum pump located within the housing of the insertion device.

In some embodiments, the first suction valve 208 a and a suction valve 208 b are operatively connected to a vacuum source (not shown in FIG. 8). In some embodiments, the first suction valve 208 a and the second suction valve 208 b are in fluid communication with a vacuum source (not shown in FIG. 8).

In some embodiments, the second infrared sensor 240 b is located adjacent to the distal ball joint 219 a and the first collar spring 216 a. In some embodiments, the third infrared sensor 240 c is located in between the first suction valve 208 a and the second suction valve 208 b.

In some embodiments, the infrared sensors are positioned elsewhere in the insertion device. In some embodiments, the infrared sensors are positioned elsewhere in the cartridge. For example, in some embodiments, the infrared sensor is positioned in the distal portion of the cartridge 234 a. In alternative embodiments, the first infrared sensor 240 a, the second infrared sensor 240 b, and the third infrared sensor 240 c are light projectors. For example, in some embodiments, the light projectors project light in the infrared wavelength spectrum. In some embodiments, the light projectors project light in the visible wavelength spectrum. In some embodiments, the light projectors project light with a wavelength ranging from about at least 400 nm to about 800 nm or more. In some embodiments, the light projectors project a laser. In some embodiments, the light projectors project light that is beyond the outer edges of the cartridge 234. In some embodiments, the first infrared sensor 240 a, the second infrared sensor 240 b, and the third infrared sensor 240 c detect light that is beyond the outer edges of the cartridge 234.

In some embodiments, the light projectors project a light in the visible spectrum onto the surface of the skin of the patient while the cartridge and/or the insertion device are separated from (e.g., not in contact with) the surface of the skin. In some embodiments, the light projectors project a light in the visible spectrum onto the surface of the skin of the patient once the cartridge is connected to the insertion device. In some embodiments, the user activates the light projectors and projects the light onto the surface of the skin of the patient in order to identify where the target blood vessel (e.g., a vein) is located. In some embodiments, a visible light image is displayed on the display screen. In some embodiments, the visible light image comprises an approximate location of a needle insertion point on the surface of the skin (e.g., an insertion indicator marking) and/or a linear needle insertion line (e.g., an indicator line).

In some embodiments, the open end of the semicircle remains tightly opposed to one another through friction, adherent surfaces, and an angular force created by a wing spring 268, a first release tab 272 a, and a second release tab 272 b. The inferior surface, which corresponds to the distal end of the wire or catheter, is coated with an adhesive and has a rough surface, which binds to the skin of the patient after being deployed.

In some embodiments, the skin attachment cup 262 comprises a first wing leg 266 a and a second wing leg 266 b. In some embodiments, the first wing 266 a and the second wing 266 b are semi-rigid. In some embodiments, the first wing leg 266 a and the second wing leg 266 b are less flexible than the first grip 264 a and the second grip 264 b. In some embodiments, the first wing leg 266 a and the second wing leg 266 b distribute the mechanical forces produced by the wing spring 268, the first release tab 272 a, and the second release tab 272 b. In some embodiments, the first wing leg 266 a and the second wing leg 266 b distribute the linear force generated by the wing spring 268 in an arc shape, thereby creating an angular force on the first grip 264 a and the second grip 264 b. In some embodiments, the first wing leg 266 a and the second wing leg 266 b create a centripetal force on the arc created between the first grip 264 a and the second grip 264 b.

In some embodiments, the skin attachment cup 262 comprises the wing spring 268. In some embodiments, the wing spring 268, when extended, pushes the first wing 266 a and the second wing 266 b outward.

In some embodiments, the first wing 266 a and the second wing 266 b are pulled apart when the user compresses the first release tab 272 a and the second release tab 272 b. In some embodiments, the wing spring 268 exerts a linear force on the first release tab 272 a and the second release tab 272 b in opposing directions, away from the center of the wing spring 268. In some embodiments, the first release tab 272 a and the second release tab 272 b are attached firmly to the cylinder 274, such that the wing spring 268 exerts a linear force on the first release tab 272 a and the second release tab 272 b. In some embodiments, the linear force creates an angular and/or rotational force which further creates a rotational force on the first grip 264 a and the second grip 264 b with respect to one another. In some embodiments, the linear force creates an angular and/or rotational force which further creates an angular and/or centripetal force on the cylinder 274.

In some embodiments, the frictional and adherent surface of the cylinder 274, which together with the centripetal force caused by the wing spring 268, the first release tab 272 a, and the second release tab 272 b, holds a catheter and/or a guidewire in place with respect to the skin attachment cup 262.

In some embodiments, the skin attachment cup 262 comprises an opening 270. In some embodiments, the medical instrument (e.g., a needle, a catheter, a cannula, and/or a guidewire) exits and/or enters through the opening 270. In some embodiments, the user applies an inward directed force on the first release tab 272 a and the second release tab 272 b, thereby compressing the wing spring 268. In some embodiments, compression of the wing spring 268 produces an outward angular force on the first grip 264 a and the second grip 264 b. In some embodiments, the outward angular force on the first grip 264 a and the second grip 264 b causes the adherent connection between the first grip 264 a and the second grip 264 b to break. In some embodiments, the outward angular force on the first grip 264 a and the second grip 264 b causes the first grip 264 a and the second grip 264 b to separate. In some embodiments, the outward angular force on the first grip 264 a and the second grip 264 b causes the cylinder of 274 to open, thereby releasing the catheter and/or the guidewire. In some embodiments, the outward angular force on the first grip 264 a and the second grip 264 b creates an outward and vertical force (i.e., along the z-axis) on the first grip 264 a and the second grip 264 b, thereby pulling the majority of the skin attachment cup 262 off of the surface of the skin. In some embodiments, the outward angular force on the first grip 264 a and the second grip 264 b disconnects the first grip 264 a and the second grip 264 b. In some embodiments, of the rest of the skin attachment cup 262 is easily pulled off of the remaining surface of the skin by pulling of the skin attachment cup 262 by the user.

In some embodiments, before use, the skin attachment cup 262 adheres to the catheter and/or guidewire while the catheter sits in its initial resting position. In some embodiments, the skin attachment cup 262 is attached to the surface of the skin once the catheter and/or guidewire are advanced to its full insertion position. In some embodiments, the skin attachment cup 262 holds the catheter and/or guidewire to the surface of the skin with enough force to overcome a withdrawing of the needle through the interior surface of the catheter lumen.

When the user chooses to perform a certain procedure, the user can select a cartridge with a shape intended for use for that procedure.

In some embodiments, the cartridge is shaped for peripheral venous procedures, central venous procedures, arterial procedures, abscess drainage procedures, biopsy procedures, joint procedures, nerve procedures, spinal procedures, chest tube procedures, cardiac procedures, other thoracic procedures, cricothyroidotomy procedures, other neck procedures, abdominal paracentesis procedures, bladder procedures, other abdominal procedures, other extremity procedures, other head procedures, osseous procedures, other procedures, a procedure involving a certain approach of the device relative to body, a subset of any of these procedures, or any combination thereof.

In some embodiments, the shape and external of the cartridge is intended for peripheral venous procedures. In some embodiments, this cartridge has a slight curvature on the bottom of the device in the horizontal plane relative to the body of the device, such that the curvature allows for better contact between the lower surface of the cartridge and the skin surface of an extremity. This shape allows for the imaging component to move substantially in the longitudinal direction and horizontal directions, change axis direction relative to the surface of the skin, change vertical location, among other useful movements. This shape would provide a more comfortable positioning of the user. The shape would also allow the user to activate the vacuum components of the cartridge or device in a more useful manner, with vacuum area at the distal end of the device to provide a more effective tourniquet effect on the vessels running longitudinal relative to the body of the device, while providing stability of the device in the longitudinal plane relative to the longitudinal plane of the extremity. In other embodiments, the cartridge may have a different shape to optimize different aspects of this procedure.

In some embodiments, the shape of the cartridge is intended for central venous access. In some embodiments, the cartridge intended for central venous procedures, has a bottom surface that is slightly curved in the horizontal direction. In some embodiments, the cartridge shape also includes a longer proximal portion of the cartridge in the vertical as compared to the front portion of the cartridge, and a shorter bottom side compared to some other cartridges. The shape is such that the bottom portion of the device is angled relative to the patient's skin surface, with the posterior aspect of the device is farther from the surface of the skin. This shape can make it easier for the user to insert the needle at a more acute angle, as the central venous structures are located deeper than peripheral structures and increases the likelihood of procedural success. The smaller bottom surface of the cartridge in this embodiment, can make it easier for the user to perform the procedure on areas of the patient that have limited skin surface available, such as the side of the neck when accessing the internal jugular vein among other locations. In other embodiments, the cartridge intended for central venous access may have a different shape to optimize different aspects of this procedure.

In some embodiments, the shape of the cartridge is intended for arterial procedures. In some embodiments, the bottom of this cartridge has a significantly shorter bottom in the longitudinal direction as opposed to top side. This can decrease the longitudinal surface area of portion of the cartridge to allow better access the arteries of the wrist, which have a limited accessible area in the longitudinal direction in some patients. In other embodiments, the cartridge intended for arterial access may have a different shape to optimize different aspects of this procedure.

In some embodiments, the shape of the cartridge is intended for joint procedures. In some embodiments, the shape of the cartridge is intended specific to a subsegment of these procedures. In some embodiments, the shape of the cartridge is intended for knee procedures. In some embodiments, there is a curvature in a portion of the bottom side of the cartridge, with only the distal end of the cartridge where the imaging device images the patient's leg being curved in the longitudinal direction. This can allow the procedure to be performed with the long axis of the body of the device in a perpendicular orientation relative to the leg length direction. The needle insertion orientation can improve the likelihood of success of the procedure, while allowing for the vacuum effects of the cartridge or device to be more effective.

In some embodiments, the shape of the needle cartridge is intended for a different subsegment of the joint procedures. In some embodiments, the shape of the needle cartridge is intended for hip procedures. In some embodiments, there is a curvature in the horizontal direction on the entirety of the bottom surface of the cartridge. This allows for more stability of the device on the leg, more effective vacuum effects. In other embodiments, the cartridge intended for hip procedures may have a different shape to optimize different aspects of this procedure.

In some embodiments, the shape of the needle cartridge is intended for spinal procedures. In some embodiments, the cartridge intended for spinal procedures has a bottom surface is divided into two sections, which sit at different angles relative to the bottom of the device and to the surface of the skin. The more distal portion of the bottom surface is angled with the bottom surface facing distally, and the more proximal portion of the bottom surface of the cartridge may be angled forward as well, but at a less acute angle relative to the bottom of the device housing. This can allow for better imaging of the vertebral spinous processes and allow the angle for needle and medical device insertion to take place significantly closer to perpendicular to the skin surface, to go deeper and between those vertebral spinous processes. In this embodiment the vacuum portions of the cartridge and device are on the more distal surface of the bottom side of the cartridge. In other embodiments, the cartridge intended for spinal procedures may have a different shape to optimize different aspects of this procedure.

In some embodiments, the shape of the needle cartridge is intended for abdominal paracentesis. In some embodiments, the cartridge intended for abdominal paracentesis has a bottom shape which is curved in the horizontal axis, and the bottom side of the cartridge effacing the skin is shorter in length than the upper side which faces the device. The bottom side of the cartridge may also be angled slightly forward. This shape can improve the surface contact, the imaging angle, and increase ease of use by the user among other benefits. In other embodiments, the cartridge intended for abdominal paracentesis procedures may have a different shape to optimize different aspects of this procedure.

In some embodiments, the shape of the needle cartridge is intended for thoracic procedures, such as tube thoracostomy, thoracentesis, paracardiocentesis, or other thoracic procedures. In some embodiments, the cartridge intended for thoracic procedures has a bottom surface is divided into two sections, which sit at different angles relative to the bottom of the device and to the surface of the skin. The more distal portion of the bottom surface is angled with the bottom surface facing distally, and the more proximal portion of the bottom surface of the cartridge is angled forward as well, but at a less acute angle relative to the bottom of the device housing. This can allow for better imaging of the ribs, and allows the angle for needle and medical device insertion to take place at a steeper to the skin surface in order to go deeper and between the ribs. In this embodiment the vacuum portions of the cartridge and device are on the more distal surface of the bottom side of the cartridge. In other embodiments, the cartridge intended for thoracic procedures may have a different shape to optimize different aspects of this procedure.

In some embodiments, the shape of the needle cartridges is intended for osseous procedures, such as interosseous line placement in the extremity or sternum, or other osseous procedures.

In other embodiments, the sensors are mechanical limit switches. In some embodiments, the sensors can be combination of optical switches and mechanical limit switches. In some embodiments, the device is calibrated at the factory. In some embodiments, the device performs a calibration routine prior to each insertion.

In some embodiments, the needle stage 303 couples directly to the needle drive assembly by fasteners 309 (FIG. 14). In other embodiments, the needle stage and the needle drive assembly are built on the same body. In some embodiments, the position of the needle drive assembly is calibrated prior to insertion using the tip of the needle and a limit switch. In other embodiments, the position of the assembly is calibrated using a hall-effect sensor. In some embodiments, the tip of the needle is detected using the ultrasound internal to the device.

The needle stage may be calibrated to match the position of the needle and/or needle stage with respect to the ultrasound probe and in the corresponding image. A calibration can be done between the needle stage and the ultrasound to quantify the offset between the needle tip and the ultrasound plane. Prior to the needle insertion, the offset can be defined with reference to a physical point on the device.

To ensure a safe needle insertion, the needle stage may comprise one or more false insertion sensors to detect unacceptable levels of shock or vibration, either during or outside an insertion procedure.

In some embodiments, the device comprises false insertion sensors to detect shock or vibration above or below certain thresholds. The insertion procedure can be aborted when the shock or vibration reaches unacceptable levels to avoid false insertion, i.e. insertion into unintended target. In some embodiments, the false insertion sensors can continuously to detect any drop or impact that may affect the device's performance.

Vacuum Connection

In some embodiments, the insertion device comprises a vacuum connection. In some embodiments, the vacuum connection is located within the housing. In some embodiments, the vacuum connection comprises a vacuum connector. In some embodiments, the vacuum connection comprises a vacuum source. In some embodiments, the vacuum connection is operatively attached to the cartridge. In some embodiments, the vacuum connector is operatively attached to the cartridge. In some embodiments, the vacuum connection and the vacuum connector are operatively attached to the cartridge. In some embodiments, the vacuum connector is in vacuum communication with a vacuum source. In some embodiments, the vacuum source is configured to draw air through the needle holder opening. In some embodiments, the vacuum source is configured to draw air through the bottom surface of the cartridge.

In some embodiments, the cartridge 234 comprises a suction area 210. In some embodiments, the suction area 210 is the entire base of the cartridge. Alternatively, in some embodiments, the shape of the suction area 210 is a shape that serves to increase the likelihood of successful cannulation of the target tissue. For example, in some embodiments, the suction area 210 is a linear area of suction on the distal end of the insertion device (e.g., of the cartridge) that causes a tourniquet-like action on underlying tissue and vessels, thereby distending the portion of a lumen of one or more blood vessels in the target tissue.

In some embodiments, the suction is created by a vacuum source within the insertion device itself. In some embodiments, the vacuum source is a vacuum motor. In some embodiments, the vacuum motor creates a vacuum between the insertion device and a flexible portion of the cartridge, thereby creating a vacuum between the cartridge and the surface of the skin of the patient. In some embodiments, the suction is created by a pneumatic manipulation of the insertion device on a flexible portion of the cartridge (i.e., the vacuum button and/or the vacuum bulb described elsewhere herein). In some embodiments, the suction is created by a pneumatic manipulation of one or more one-way suction valves, thereby creating a vacuum between the cartridge and the surface of the skin of the patient.

In some embodiments, the suction is created by mechanical manipulation of the insertion device on the cartridge by a plurality of one-way valves and bulbs. In some embodiments, the plurality of one-way valves and bulbs transmit a force on interconnected flexible portions of the cartridge base, such that a vacuum action is created under the cartridge. In some embodiments, the suction is created by mechanical manipulation directly on the cartridge by the user. For example, in some embodiments, the user mechanically manipulates a bulb connected to one or more one-way valves, thereby creating a vacuum transmitted directly to the surface of the skin of the patient. Alternatively, in some embodiments, the vacuum is transmitted to the flexible portion of the cartridge, thereby creating a vacuum between the cartridge and the surface of the skin of the patient.

In some embodiments, the shape of the suction area is changed and/or adjusted during the course of an insertion procedure, such that it maximizes that success of the procedure (e.g., targeting the target tissue location). In some embodiments, the intensity of the suction is changed and/or adjusted during the course of an insertion procedure, such that it maximizes that success of the procedure (e.g., targeting the target tissue location).

In some embodiments, a suction device is connected to the cartridge. In some embodiments, the suction device is located externally with respect to the insertion device and the cartridge. In some embodiments, the suction device is used to create a vacuum for a medical procedure (e.g., a needle insertion). In some embodiments, the suction is created by mechanical manipulation of the suction device on the cartridge. For example, in some embodiments, the cartridge comprises flexible components that are integrated with rigid components that are pulled, in order to create a suction cup-like action. In some embodiments, the cartridge comprises the suction device. In some embodiments, having the suction device located within the cartridge (as opposed to having the suction device located within the housing of the insertion device) prevents and/or ameliorates the risk of a potential contamination of the insertion device (e.g., accidental suction of blood from the surface of the skin and into the insertion device). Furthermore, in some embodiments, the insertion device comprises an actuator that activates the suction device (e.g., depresses the vacuum button and/or vacuum bulb). In some embodiments, the actuator comprises a barrier (e.g., a casing) that protects it from a potential contamination (e.g., a blood contamination). In some embodiments, the automatic activation of the suction device by the actuator prevents and/or decreases the risk of user error when activating the suction device (e.g., the user not deactivating suction when blood is present on the surface of the skin). In some embodiments, the automatic activation of the suction device by the actuator prevents and/or decreases the risk of a potential contamination of the insertion device (e.g., a blood contamination) caused by user error.

Next, in some embodiments, the method comprises imaging the target tissue using the ultrasound probe and the infrared sensor by contacting the surface of the skin of the individual with the bottom surface of the cartridge. In some embodiments, the user uses the ultrasound probe to target the tissue. In some embodiments, the user activates the infrared sensor to target the tissue. In some embodiments, the user obtains an ultrasound and/or infrared image by contacting the skin of the individual with the bottom surface of the cartridge. In some embodiments, the user images the target tissue remotely.

Next, in some embodiments, the method comprises identifying the needle insertion point on the display screen. In some embodiments, the user identifies the needle insertion point via the indicator marking 128 on the display screen. In some embodiments, the user actives a vacuum source to create a negative pressure around the target tissue insertion area at the surface of the skin of the patient. In some embodiments, the vacuum source provides tension within an area of suction. In some embodiments, a vacuum suction pump motor is activated to create suction. In some embodiments, the user activates a vacuum source via depression of a physical button or activation of a switch on the insertion device. In some embodiments, the amount of negative pressure applied to the surface of the skin of the patient is automatically regulated by the insertion device. For example, in some embodiments, the insertion device outputs the negative pressure applied on the display screen. In some embodiments, the computing device of the insertion device uses a feedback loop system to automatically regulate, activate, and/or deactivate a vacuum source. In some embodiments, the vacuum suction pump motor exerts a pulling force against the skin of the individual. In some embodiments, the vacuum source replicates the physical tension typically and mechanically induced by a health care worker (e.g., by holding the skin of the patient taut and/or by using a tourniquet prior to insertion of a needle).

Next, in some embodiments, the method comprises adjusting the needle holder angle and moving the needle longitudinally, through the cartridge inlet, thereby introducing the needle at the needle insertion point and into the target tissue. In some embodiments, adjusting the needle holder angle and moving the needle longitudinally are manually actuated. In some embodiments, adjusting the needle holder angle and moving the needle longitudinally are remotely actuated. In some embodiments, adjusting the needle holder angle and moving the needle longitudinally are automatically actuated by the computing device. In some embodiments, the method comprises administering a therapeutic agent using the needle. In some embodiments, the method comprises collecting a biopsy sample using the needle. In some embodiments, the method comprises inserting a guidewire into the target tissue. In some embodiments, the method comprises retracting the guidewire from the target tissue. In some embodiments, the method comprises inserting the catheter into the target tissue. In some embodiments, the method comprises retracting the catheter from the target tissue.

In some embodiments, the user implements the user interface to adjust the longitudinal location of the needle. In some embodiments, the user implements the user interface to adjust the needle holder angle via an angle actuator. In some embodiments, the user interface (e.g., the display screen, the gear wheel, or the positioning dial) of the insertion device is used to adjust the longitudinal location of the needle and/or the needle holder angle. In some embodiments, the user initially adjusts the longitudinal location via the user interface. In some embodiments, the user proceeds by adjusting the angle of the needle. In some embodiments, the user introduces the needle at the selected insertion point and into the target tissue. In some embodiments, the user inserts the needle into the selected tissue via the needle insertion button. In some embodiments, the user uses a digital selection method via the display screen to adjust the location, angle, and/or position of the needle. In some embodiments, the needle is guided and/or inserted into the target tissue via the vacuum-assisted insertion system. For example, in some embodiments, the user turns on the vacuum source in order to create vacuum between the insertion device and the cartridge, thereby creating a vacuum between the cartridge and the skin of the patient. In some embodiments, the suction is created by mechanical manipulation of the insertion device and the cartridge. For example, in some embodiments, the cartridge comprises flexible features integrated with more rigid elements that when pulled away from the patient, they create a suction cup-like action.

The method can further comprise adjusting the position of the needle holder with respect to the needle stage. The needle stage may comprise a series of actuators around a specific coordinate system in order to obtain the required degrees of freedom for insertion. The coordinate system can require at least two, three, four, or five degrees of freedom that can allow the needle to puncture the skin at the required orientation for an intravenous insertion, with positional feedback from the ultrasound. The needle stage can then reduce the angle between needle and the vein's central axis, while maintaining the needle tip position within the lumen using reverse kinematics equations. The needle stage can further allow the needle to be advanced along the length of the lumen of the vein while maintaining a central position within the lumen.

In some embodiment, it may be possible that the force applied on the needle results in deflection of the needle tip off its central axis during the insertion. A longitudinal ultrasound scan can allow the needle deflection to be visually recognized and insertion path adjusted in real time either automatically or manually.

In some embodiments, the needle insertion system can visually interpret in real-time the current position and deflection of the needle tip using a combination of longitudinal and transverse ultrasound scans. In some embodiments, the interpretation is used to compensate error in the insertion position. In some embodiment, the interpretation is used as a visual indicator for the operator, allowing them to adjust the needle. In other embodiments, the interpretation is used in any combination thereof.

In some embodiments, the imaging stage can be used to manipulate the position of the ultrasound probe and the infrared sensor with respect to the housing. During insertion and once the tip of the needle has entered the vessel lumen, the user may adjust the imaging stage to move the ultrasound probe and the infrared sensor to locate a second target. The second target may be an advanced section along the length of a vessel lumen. The needle stage can be adjusted to allow the needle to move to the advanced section while maintaining a central position within the lumen. The needle can be pivoted co-axially with the vessel and can subsequently release the catheter. To minimize the risk of tearing the outer wall of the vessel during the pivoting process, the insertion system can create a virtual pivot point at or around the intersection of the vessel wall and the needle. In another embodiment, the needle can be pivoted about the needle tip. In some embodiments, the device can interpret the ultrasound image to create a virtual pivot point at or around the intersection of the vein wall (tunica externa) and the needle body in order to minimize the risk of tearing the tunica externa during the insertion process.

Needle Insertion Algorithm

The needle insertion system can be used to determine the required needle insertion path of during the insertion process. The designated insertion path can be followed to place the needle and catheter within the lumen of the target vessel. The insertion path can be driven by an algorithm developed for the insertion device.

In some embodiments, the needle insertion algorithm for the insertion system can be generalized in 3D space as a 6+ Degree Of Freedom (DOF) system.

The insertion system can operate under a designed needle tip path, defined as: N=({right arrow over (x)},{right arrow over (n)})

-   -   Where: {right arrow over (x)} is the needle tip position;     -   {right arrow over (n)} is the vector direction pointing         coaxially along the needle; and     -   Both {right arrow over (x)} and {right arrow over (n)} are         parametrized as {right arrow over (x)}(S), {right arrow over         (n)}(S). S is defined as the % of path for a given step.

The required needle path can be inputted into the insertion system by the user and the inputs can be translated and relayed by the insertion system to an actuator space defined as: U=(A,B,C,D, . . . )

In the given actuator space, user inputs can set the joint position/velocities through reverse kinematics. The operating principle for the insertion system can be a rigid body assumption as shown in FIG. 20.

The needle insertion algorithm can provide detailed steps of the needle path starting from the docked position. FIG. 18 illustrates the needle in the docked position. A and B are actuators that can drive the needle. The detailed steps can include mathematical equations and structures involved in the process. The equations disclosed herein can be adapted depending on the required input into the actuators.

In some embodiments, the needle docked position can be defined as below: T(X _(d) ,Y _(d),θ_(d))=Tip Docked Position T(X _(d) ,Y _(d),θ_(d))=Tip Docked Position

The ultrasound plane can be centered over V(X, Y, Z), where: Y=Vessel Depth. The origin may be defined at the ultrasound probe head. For 2D problem, Z can be equal to 0.

Stage 1: Horizontal Needle Tip Positioning

In the first stage, the needle tip position can be adjusted along the x-axis. In some embodiments, the needle tip is positioned such that when it rotates to the insertion angle, the needle body is lined up with the target vessel position V.

The needle tip can be adjusted via actuator B along the x-axis by a given displacement X as shown in Error! Reference source not found. FIG. 19B shows the movement of the needle for horizontal needle tip adjustment. The required position of X can be defined by the following equation and insertion angle.

$\frac{V_{y} + Y_{d}}{X_{d} + X} = {\tan\;\theta_{I}}$ θ_(I) = Insertion  Angle  ( ∼ 30^(∘))

Where: V_(y) is the vertical distance from the Ultrasound Probe head to the target vessel;

-   -   Y_(d) is the vertical distance from the needle tip to the         Ultrasound Probe head; and         -   X_(d) is the starting positon of the needle tip along the X             axis.

The insertion angle can be determined by the insertion parameters set by the user or defined by the insertion device. The required movement distance of actuator B can be defined as X given the equation:

$X = {\frac{V_{y} + Y_{d}}{\tan\;\theta_{I}} - X_{d}}$ Stage 2: Needle Rotation about Tip to Insertion Angle

In stage two, the needle can be rotated about the needle tip to reach the insertion angle θ₁ defined by the user or the insertion system.

Each actuator can be adjusted in actuator space U (A, B C) to rotate the needle (FIG. 19C), given the following equations as a function of needle tip position θ, X, Y. C(θ,X,Y)=θ B(θ,X,Y)=B·+L _(c) sin θ−L _(N) cos θ A(θ,X,Y)=A·+L _(c) cos θ−L _(N) sin θ

-   -   Where: B· is the starting position of the B actuator during         stage 2;         -   A· is the starting point of the A actuator during stage 2;

L_(c) is the length of the arm of actuator C (centerline of needle to center of rotation for C);

-   -   and     -   L_(N) is the length of the needle.         Stage 3: Inserting Needle to Vein

In stage three, the needle can be inserted by an insertion distance defined by the parameter S. The needle tip can start at position 0 and end at position S when the needle tip is inside the target vessel (FIG. 19D).

The value of S can be defined as: S=√{square root over ((V _(y) +Y _(d))²+(V _(x) −X _(d))²)}

Where: V_(y) is the vertical distance from the Ultrasound Probe head to the target vessel.

-   -   Y_(d) is the vertical distance from the needle tip to the         Ultrasound Probe head.     -   X_(d) is the horizontal position of the needle tip from the         Ultrasound Probe head.     -   V_(x) is the horizontal position of the vessel from the         Ultrasound Probe head.

Given S, the actuator space equations for actuator A and B can be defined as below: B(θ,X,Y)=S*cos θ+X ₁ C(θ,X,Y)=−S*sin θ+Y ₁

As the needle insertion goes from 0→S, actuator C can remain at θ₁.

Stage 4: Needle Lowered from Insertion Angle

In stage four, the needle can be rotated by the needle tip to lower its insertion angle to some defined angle (θ_(v)) for advancing into the lumen. The equations for rotations to θ_(v) can be the same as in stage two.

For stage four, the value of angle θ_(v) can depend on the patient's anatomy. It may not be possible to achieve a θ_(v)=0, rather θ_(v) may be θ_(v)>0. C=θ _(v)<θ₁&&θ_(v)>0 B(θ,X,Y)=B·+L _(c) sin θ−L _(N) cos θ±X _(f) A(θ,X,Y)=A·+L _(c) cos θ−L _(N) sin θ+Y _(f) Y _(f) =−ΔY _(d)

One likely phenomenon the needle could experience is the fencepost effect. When trying to pivot the needle about the needle tip within an elastic medium (human tissue), the needle can experience a bending moment somewhere between the needle tip and the base of the needle. The bending moment may result in a deflection of the needle body, causing the needle tip to drift from the vessel center. A solution to the fencepost effect can include some adjustment of Y_f to account for the drift in needle tip position along the Y axis. There may also be some adjustment required in the X axis due to the fencepost effect defined as X_f.

Y_(f) or X_(f) would be applied manually by an operator or automatically through detection of the needle tip using ultrasound.

Stage 5: Advancing Needle into Lumen

In stage five, the needle is advanced along the lumen of the vessel. The needle can be advanced along the centerline of the vessel defined as V^(→) (FIG. 19E). V^(→) can be calculated using a sweep of the ultrasound when the device is placed, or in real time by the user during advancement of the needle.

EXAMPLES Example 1: Venous Blood Withdrawal Using an Insertion Device

A health care worker performs a venous blood withdrawal on a patient using the insertion device described herein. The health care worker inserts the peripheral intravenous site and phlebotomy cartridge 174 into the cartridge receiver of the insertion device. The health care worker inserts the collection tube into the port, which allows the collection tube to be in fluid communication with the needle. The health care worker then presses the bottom surface of the cartridge onto the left arm of the patient. With the sensor areas in place, the ultrasound probe and the infrared sensor generate an image of the blood vessels of the left arm of the patient. The ultrasound image and the infrared image are shown as an overlay image and displayed on the display screen. The health care worker adjusts the placement of the insertion device, guided by the image displayed on the display screen, until she identifies the median cubital vein in the antecubital fossa in the left arm of the patient. The image displayed on the display screen also shows an indicator line and insertion indicator marking to allow for identification of the needle insertion point. The health care worker activates the vacuum motor by pressing the vacuum seal button on the insertion device. Activation of the vacuum motor creates suction between the insertion device and the surface of the skin of the patient in the needle insertion region of the left arm of the patient. The health care worker adjusts the angle of the needle by using the gear wheel of the insertion device. The health care worker adjusts the longitudinal position of the needle by using the positioning dial of the insertion device. The health care worker inserts the needle at the proper point of insertion by depressing the needle insertion button of the insertion device. Once the needle is inserted into the patient, the insertion device displays the position of the needle in real time on the display screen. The health care worker ensures the needle enters the median cubital vein and begins collecting venous blood into the collection tube upon accessing the lumen of the vein. Once a sufficient venous blood volume is collected, the health care worker withdraws the needle by pressing the needle withdrawal button.

Example 2: Venous Injection Using an Insertion Device

A health care worker performs an injection on a patient using the insertion device described herein. The health care worker inserts the cartridge into the cartridge receiver of the insertion device. The health care worker then presses the cartridge onto the left arm of the patient. With the sensor areas in place, the ultrasound probe and the infrared sensor generate an image of the blood vessels of the left arm of the patient. The ultrasound image and the infrared image are shown as an overlay image and displayed on the display screen. The health care worker adjusts the placement of the insertion device, guided by the image displayed on the display screen, until she identifies the median cubital vein in the antecubital fossa in the left arm of the patient. The image displayed on the display screen also shows an indicator line and insertion indicator marking to allow for identification of the needle insertion point. The health care worker activates the vacuum motor by pressing the vacuum seal button on the insertion device. Activation of the vacuum motor creates suction between the insertion device and the surface of the skin of the patient in the needle insertion region of the left arm of the patient. The health care worker adjusts the angle and the position of the needle. The health care worker inserts the needle at the proper point of insertion by depressing the needle insertion button of the insertion device. Once the needle is inserted into the patient, the insertion device displays the position of the needle in real time on the display screen. The health care worker ensures the needle and catheter enters the median cubital vein. Once the needle and the catheter enter the vein, the health care worker triggers releasing mechanism to detach the catheter from the insertion device and withdraw needle away from the vein by pressing withdrawal button. A medication is infused through the catheter. Once a sufficient amount of medication is infused, the health care worker withdraws the catheter. Alternatively, the health care worker connects a syringe the needle and injects medication through the needle without using the catheter.

Example 3: Lumbar Puncture Using an Insertion Device

A health care worker performs a biopsy on a patient using the insertion device described herein. The health care worker inserts the cartridge into the cartridge receiver of the insertion device. The health care worker inserts the collection tube into the port, which allows the collection tube to be in fluid communication with the needle. The health care worker then presses the bottom surface of the cartridge into the spinal column of the patient. With the sensor areas in place, the ultrasound probe and the infrared sensor generate an image of the spinal column of the patient. The ultrasound image and the infrared image are shown as an overlay image and displayed on the display screen. The health care worker adjusts the placement of the insertion device, guided by the image displayed on the display screen, until she identifies a proper insertion site. The image displayed on the display screen also shows an indicator line and insertion indicator marking to allow for identification of the needle insertion point. The health care worker activates the vacuum motor by pressing the vacuum seal button on the insertion device. Activation of the vacuum motor creates suction between the insertion device and the surface of the skin of the patient in the needle insertion region. The health care worker adjusts the angle of the needle by using the gear wheel of the insertion device. The health care worker adjusts the longitudinal position of the needle by using the positioning dial of the insertion device. The health care worker inserts the needle at the proper point of insertion by depressing the needle insertion button of the insertion device. Once the needle is inserted into the patient, the insertion device displays the position of the needle in real time on the display screen. The health care worker ensures the needle enters the spinal cord and begins collecting cerebrospinal fluid into the collection tube upon accessing the cavity of the spinal cord. Once a sufficient cerebrospinal fluid is collected, the health care worker withdraws the needle by pressing the needle withdrawal button.

Example 4: Abdominal Paracentesis Using an Insertion Device

The patient is placed in a supine position with lower extremities covered by a sheet and the arms preferably held above their head. The user assumes a position lateral to the left side of the patient's abdomen. Then the area on the left lateral frontal aspect of the lower abdomen, slightly inferior to the umbilicus at the lateral position in alignment with the anterior axillary line is broadly sterilized using betadine, chlorohexidine, or another fluid for sterilization. The specific cartridge intended for paracentesis procedures is removed from its sterile packaging in sterile fashion and attached to the bottom surface of the housing. The sensors on the housing which recognize the type of cartridge attached send a signal to the onboard computer, and the computer processes this information then sends a signal to control the ultrasound probe and displays screen to their standard initial positions, and the ultrasound probe assumes a horizontal position within the device that is a set distance longitudinally from the proximal most possible ultrasound probe position within the housing and the displayed probe depth is automatically adjusted to the preferred depth for the paracentesis procedure. The sterile sleeve connected to the cartridge is then pulled over the entirety of the device by the user, such that the sleeve creates a sterile barrier between the user and all of the buttons, handles, controls, and displays of the device. The user then places the bottom of the device (which has the attached cartridge) on the patient's left lower abdomen. The curvature of the bottom of this cartridge is semi-circular such that the curve is oriented in the horizontal direction. The user then moves the device about this area of the abdomen searching for the largest area of free fluid within the abdomen. When the area of maximum ascites is identified, the device is oriented such that the largest area of fluid coincides with the center vertical line on the display screen. The device's targeted vacuum suction is then activated, such that there is a vacuum suction created on the bottom the cartridge, effectively attaching the cartridge and device to the abdominal wall and distorting the soft tissue under the vacuum regions. While remaining attached to the abdomen, the user controls the probe position while the probe remains in horizontal orientation within the housing, the user does a longitudinal sweep with the probe going both proximal to the initial position and then distal before returning the probe to the initial position. The user can activate the doppler affect of the device before the sweep such that vessels which may lie in the path of the needle can be identified and the device detached and adjusted if necessary. The user may choose to select the small needle, and target the tissue in the planned path for the large needle, and inject lidocaine into this area. If the anticipated path of the needle appears safe, the user then adjusts the target location of the needle presented on the display screen of the needle to an area within the free fluid just below the interior wall of the abdominal cavity. Once targeted, the needle advancement is triggered by the user which sends a signal to the onboard computer. The signal is computed, and then an outgoing signal from the computer is sent to the actuators and needle position portions of the device to change the angle, position, and advancement of the needle so that the needle tip advances in a chosen angle to the targeted location. If the user decides to advance the needle further, the probe position can then be changed by the user to a more distal location, and this process repeated one or more times, such that the needle tip is advanced farther into the ascites fluid. Once the needle tip is in a satisfactory location, the user can attach tubing to the side port of the cartridge which is attached inside of the device to fluid tubing and the needle, and fluid can be drawn out of the patient's abdomen using a syringe, vacuum bottle, wall suction or other device. Alternatively, the user may choose the initial target of the large needle to be just superior to the interior border of the abdominal wall, a small distance from that tissue layer, then activate a safety needle within the lumen of the large needle to extend to a further target location, thereby piercing the internal aspect of the abdominal wall without risking penetration into a loop of bowel or other intra-abdominal organ. Medication or fluids can be injected into the abdominal fluid within the cavity. Alternatively, tubing can be connected to the external port of the cartridge, and fluid can be drained. Another option for the user once the needle tip is advanced to a satisfactory location, is that a catheter can be advanced over the needle into the abdominal fluid and exterior portion of that catheter attached to the exterior abdominal wall, and the user can press the end procedure button and the device can be removed.

Example 5: Knee Joint Injection Using an Insertion Device

The patient is placed in a supine position with the knee in a slightly flexed position. The area on the front on the leg just proximal to the patella is broadly sterilized using betadine, chlorohexidine, or another fluid for sterilization. The specific cartridge intended for knee injections is removed from its sterile packaging in sterile fashion and attached to the bottom surface of the housing. The sensors on the housing which recognize the type of cartridge that has been attached sends a signal to the onboard computer, and the computer processes this information then sends a signal to control the ultrasound probe into its standard initial position, and the ultrasound probe assumes a horizontal position within the device a set distance longitudinally from the proximal most possible ultrasound probe position within the housing. The Sterile sleeve connected to the cartridge is then pulled over the entirety of the device by the user, such that the sleeve creates a sterile barrier between the user and all of the buttons, handles, controls, and displays of the device. The user then places the bottom of the device (which has the attached cartridge) on the patient's leg, just proximal to the patella. The curvature of the bottom of this cartridge is semi-circular such that the curve is oriented in the same direction of curvature of the leg, with the curvature varying in the longitudinal plane and the ultrasound probe is in a parallel orientation relative to the femur of the patient. The user then moves the device about the leg, such that the cartridge remains in contact with the leg, and the displayed image is viewed by the user, and the movement is stopped when the supra-patellar pouch is aligned with the center line of the image. While the device remains still on the patient, the ultrasound probe rotation knob is then turned, such that the ultrasound probe is turned 90 degrees relative to the housing, and then the probe and ultrasound plane sits in a perpendicular plane relative to the femur and longitudinal plane relative to the device. The position of the device can again be adjusted by the user at this time, so that the needle target line is aimed at the supra-patellar pouch. The device's targeted vacuum suction is then activated, such that there is a vacuum suction created on the bottom the cartridge, effectively attaching the cartridge and device to the leg and distorting the soft tissue under the vacuum regions. While remaining attached to the leg, the user puts gentle traction on the device slightly distally down the leg and slightly laterally relative to the leg, thereby effectively consolidating and pushing the suprapatellar fluid into a more concentrated position and making it easier to target with the needle. The needle path and distal end point is then selected using the controls targeting the central fluid area within the suprapatellar pouch, and the needle advance button is pressed, which causes the needle within the cartridge to advance into the patient's leg through the selected path and the needle advancement stops at the selected needle endpoint. The user can select a new target endpoint and plane of entry within the knee, and the needle can be advanced again by the user pressing the needle advancement button. With the needle tip well within the supra-patellar pouch, the port and flow tubing connected to the needle can be accessed, and fluid can be drawn out into a syringe, or a syringe containing liquid can be attached and used to inject that liquid into the knee. Fluid can be withdrawn from the pouch, liquid can be injected into the pouch, or both of these steps can be taken with one or more syringes or tubes. The End or abort button can be pressed by the user to withdrawal the needle, and the vacuum suction can then be stopped can device released from the leg of the patient.

Example 6: Thoracostomy Tube Placement Using an Insertion Device

The patient is placed in a supine position with lower extremities covered by a sheet and the arms preferably held above their head. The user assumes a position lateral to the left side of the patient's chest wall. At the left mid-axillary line and the 4th or 5th rib space, the skin is broadly sterilized using betadine, chlorohexidine, or another fluid for sterilization, and sterile drapes are placed on the patient. The specific cartridge intended for thoracostomy procedures is removed from its sterile packaging in sterile fashion and attached to the bottom surface of the housing of the device. The shape of the thoracostomy procedure cartridge has two portions to the bottom surface, with the more proximal portion angled distally and the more distal portion angled distally at a steeper angle than the proximal portion. The more distal end of the cartridge contains an array of vacuum suction areas. The sensors on the housing, which recognize the type of cartridge have been attached, send a signal to the onboard computer, and the computer processes this information then sends a signal to control the ultrasound probe and display screen to their standard initial positions, and the ultrasound probe assumes a longitudinal position within the device a set distance longitudinally from the proximal most possible ultrasound probe position within the housing and the displayed probe depth is automatically adjusted to the preferred depth for the thoracostomy procedure. The sterile sleeve connected to the cartridge is then pulled over the entirety of the device by the user, such that the sleeve creates a sterile barrier between the user and all of the buttons, handles, controls, and displays of the device. The user then places the distal portion of the bottom of the cartridge on the left lateral chest wall at the 5th intercostal space in the mid-axillary line and orients the device to be perpendicular to the ribs. The user then moves the device about this area of the chest wall to identify an ideal position of the device. Once identified, the user activates the vacuum suction, tightly adhering the cartridge and device in place on the chest wall. The device's targeted vacuum suction is then activated, such that there is a vacuum suction created on the bottom the cartridge, effectively attaching the cartridge and device to the abdominal wall and distorting the soft tissue under the vacuum regions thereby stabilizing the skin and tissue at the ultrasound probe location. While remaining attached to the chest, the user sweeps the probe in the horizontal and longitudinal directions. When the user has found a desirable target location, just superior to one of the ribs, the user selects and activates the small needle within the cartridge. The user then targets the area planned for tube insertion, and activates the insertion of the small needle to this area in a superficial position under the skin surface. The user then selects the amount of lidocaine to dispense from the prefilled sterile container within the cartridge and injects the medication. The user then advances the small needle repeating these steps and injects more doses of the anesthetizing medication before selecting to withdraw the small needle using the controls on the device. The user then activates the large needle, and determines the most desirable path and target, with the path coursing at an angle of approximately 80 degrees just superior to the rib and target just within the plural cavity, controlling these with the device controllers. The user then activates the insertion of the long needle to that position. These steps can be repeated and the needle further inserted. Once the needle is in satisfactory position, the user can choose on the device to then advance the thoracostomy guidewire that is preloaded in the cartridge, or advance a small thoracostomy tube over the needle for an emergent or temporizing thoracic decompression. after the guidewire is advanced, the user can choose to end the procedure by selecting and pressing the end button on the device, which withdraws the needle to a locked position within the cartridge, releases the vacuum, and can release the guidewire from the cartridge. After which time the user can continue the tube thoracostomy procedure using the Sledinger technique.
